Fast Refresh is a React feature that allows you to get immediate feedback for changes in your React components. If you edit a file that only exports React components, Fast Refresh will update the code only for that file, and re-render your component.
Rakkas extends this concept slightly to allow Fast Refresh on pages and layouts even if they have a load function. The load function will be called again every time you change the source file.
⚠️ You should not export any value other than your page or layout definition from page and layout source files. Exporting types is OK.
